Between the split portions of said finger I extend the shank 35 of a brush or other similar device 36. The shank extends in a direction generally transverse to the belt so that by adjustment of the finger longitudinally of the shank the bristles of the brush may be nio-ved toward or from the belt, as will be clearly apparent from Fig. 1.

During the operation of my improvements l the bristles or brush will move'with the lay in aback and forth direction over the surface of the belt to engage anyweft end Which may beheld frictionally to the belt toremove the same. Should the belt becomeslack the arm22 may bemoved to the right and acorresponding adyustment made wlth respect to the shank 35 to insure proper engagement between the bristles and the belt. In this connection'it should be understood that the studs 12 andQl and also the lower roll 23 extend in a directionwhich is substantially parallel to the back and forth movement of the lay so that the brush. 36 is in substantial contact with the belt for the full width thereof. I

From the foregoing it will be seen that I have provideda very simple form of clear mg devlce which moves with the lay across that part of the belt to which weft ends may cling, but it will be seen that the brush is placed so as to permit a considerable length of weft to engage the belt before arriving at longitudinal adjustment of the shank 35 rel- 1 atively to the finger 32.

7.1. In a weft end tensi'oning device including, atravellingsurface movable in a given pathand adapted to engage the weft ends,

a; lay, movable in a direction transverse to the movement of the surface, and a clearer on thelay to engage the surface and remove weft ends therefrom. I

2. In a. weft end tensioning device including atravelling surfac'emovable in a given path and adapted to engage the weft ends, a lay,.movable in a direction; transverse to the movement of the surface, and a clearer on the lay to. engage the surface and, remove weft ends. therefrom, said clearer including a brush with flexible bristles to engage the surface. I

3. In a weft end tensioning device including a travelling surface movable in a given path and adapted to engage the weft ends, a lay movable in a, direction transverse to the movement of the'surface, a normally fixed support for the surface movable to assume a plurality of positions relative y to the length of the lay, and a clearer carried by the lay 7 support for the element and clearer mounted on the lay;

5; In a Weft end tensioning device for a magazine loom having a lay moving back and forth therein, a weft end engaging surface, means to move said surface intermittently to exert a frictional strain on the weft ends in contact therewith, and a clearer carried by the'lay and movable, across the surface and in a direction transverse to the movement ofthe surface to engage the weft ends and remove the same fromthesurface. 1 b6. Inaweft end tensioning .devicefor a 100110, a weft end engaging surface, means to move said surfa'cefto exert a frictional strain on the weft/ends in contact therewith, and a clearer movable across the surfaceand in a 1 direction transverse tov the movement of the surface to engage the weft, ends andremove V the same from the surface.

'7. In a weft end tensioning. device for a loom,ra weft end engaging surface,'means to move said surface intermittently to exert a frictional strain on the weft ends in contact therewith, and a clearer movable across the surface and in a direction transverse to the movement of the surface to engage the weft ends and remove the same from thesurface, said clearer being movable relatively to the surface when the latter 1s moving to exert frictional strain on thefweft.

8. In a weft tensioning device for a loom,

a friction surface to engage the weft ends to tension the same, a clearing device for the surface to remove weft'ends clinging thereto, and means to cause simultaneous movement of the surface in one direction and the clearer a direction transverse'thereto.
